It’s an ideal choice for summer barbecues, picnics, or a comforting family dinner dessert, promising a delightful treat without the stress of traditional baking.

Why You’ll Love This Slow Cooker Lemon Blueberry Cake
There’s something uniquely satisfying about slow cooker desserts, and dump cakes are at the top of that list. They are renowned for their simplicity, allowing you to “dump” the ingredients into your Crockpot and let the magic happen. This Lemon Blueberry Dump Cake stands out not only for its ease but also for its irresistible flavor profile. The vibrant lemon cuts through the sweetness of the blueberries, creating a balanced and refreshing dessert that’s perfect any time of year.
Forget the stress of precise measurements and constant oven monitoring. With this recipe, your slow cooker does all the heavy lifting, freeing you up to enjoy your time with family and friends. It’s a truly versatile dessert, equally at home as a comforting weeknight treat or a show-stopping dish at your next potluck or gathering.

Gather Your Simple Ingredients
One of the best aspects of this Crockpot Lemon Blueberry Dump Cake is its incredibly short ingredient list. You’ll only need three primary components to create this delicious dessert. Below is a quick overview; precise measurements and step-by-step instructions are provided in the full recipe card at the bottom of this article.
- Lemon Cake Mix: This serves as the dry base for our cake, infusing it with bright, citrusy flavor. It’s the ultimate shortcut to a fluffy and flavorful dessert.
- Blueberry Pie Filling: Canned blueberry pie filling is the secret to the “dump” cake’s moist, fruity layer. It provides both the fruit and the necessary liquid for the cake mix to absorb as it cooks.
- Butter: Essential for creating that delightful, crumbly, and slightly crisp topping. Butter melts down, seeps into the cake mix, and gives the cake its rich texture and golden finish.
Optional Garnishes: While delicious on its own, consider enhancing your dump cake with fresh blueberries, a few cherries, or a generous scoop of vanilla ice cream for an extra touch of indulgence.
Essential Equipment for Crockpot Baking
Making this dump cake is incredibly straightforward, but having the right tools can make the process even smoother. Here are a couple of items we recommend:
Microwave Silicone Cover: This might seem like an odd recommendation for a slow cooker recipe, but it’s a lifesaver for melting butter. If you opt for melted butter (more on that in the variations), a good silicone lid prevents those notorious butter splatters that can mess up your microwave. Keep your kitchen clean and your baking hassle-free!
Slow Cooker or Crockpot: The star of this recipe! We highly recommend using a slow cooker with a digital timer that automatically switches to a “warm” setting after the cooking time is complete. This feature is fantastic for maintaining the perfect temperature without overcooking your dessert, giving you peace of mind and perfectly cooked results every time.

How to Make This Delicious Crockpot Lemon Blueberry Dump Cake
Get ready for the easiest dessert you’ll ever make! The beauty of a dump cake is in its name – simply combine the ingredients, and your slow cooker does the rest. For complete, detailed instructions, refer to the printable recipe card at the end of this post. Here’s a quick overview of the straightforward process:
- Prepare Your Slow Cooker: Begin by lightly spraying the interior of your slow cooker with a non-stick cooking spray. This crucial step prevents the cake from sticking and makes serving and cleanup incredibly easy.
- Layer the Ingredients: First, pour the blueberry pie filling evenly across the bottom of the prepared slow cooker. Next, sprinkle the dry lemon cake mix directly over the pie filling. Don’t stir! Finally, place sliced butter pieces (or drizzle melted butter) evenly over the dry cake mix layer.
- Cook to Perfection: Cover your slow cooker and cook on the low setting for the recommended time. The butter will melt, seeping into the cake mix and fruit filling, creating a moist, tender cake with a delightfully crumbly topping.
Preparation and Storage Tips
This lemon blueberry dump cake is wonderful served warm, but it’s also incredibly versatile for make-ahead planning. After baking, simply cover the slow cooker insert with aluminum foil or plastic wrap. You can refrigerate it for a cold dessert or leave it on your countertop if you prefer it at room temperature. Its flavors only deepen with time!
- Storage: Leftovers stored in an airtight container in the refrigerator will remain delicious for up to five days. If left at room temperature, it’s best consumed within two days.
- Freezing: For longer storage, this dump cake freezes beautifully. Wrap individual portions or the entire cake securely in plastic wrap, then an additional layer of aluminum foil to prevent freezer burn. It can be frozen for up to three months.
- Reheating: To reheat, thaw frozen portions overnight in the refrigerator or on your countertop until ready. You can warm individual servings in the microwave, or gently reheat the entire cake in a low oven (around 250°F / 120°C) until warmed through.
Creative Recipe Variations to Try
While the classic Lemon Blueberry Dump Cake is delightful, this recipe is incredibly adaptable. Feel free to experiment with these variations to suit your taste or what you have on hand:
- Butter Options: Whether you use melted or sliced butter, the cake will turn out delicious. Sliced butter tends to create a slightly crispier, more defined crumble on top, while melted butter might result in a more uniform, slightly softer crust. If using melted butter, you can either pour it over the dry cake mix or gently mix it into the cake mix before spreading it over the fruit layer for a more cake-like consistency.
- Cake Mix Substitutions: Can’t find lemon cake mix? No problem! A yellow cake mix works wonderfully as a base. To infuse that bright citrus flavor, simply add the zest of one or two lemons to the dry cake mix before layering. A splash of lemon extract can also boost the flavor.
- Vegan and Vegetarian Friendly: This recipe is naturally vegetarian. To make it vegan, ensure your cake mix and blueberry pie filling are labeled as such (most canned pie fillings are vegan-friendly). Crucially, substitute the butter with a plant-based butter alternative to keep it entirely vegan.
- Gluten-Free Option: Easily adapt this recipe for gluten-free diets by opting for a certified gluten-free lemon cake mix and ensuring your blueberry pie filling is also gluten-free. The preparation method remains exactly the same!
- Scaling for Crowds: Serving a larger group? This recipe is simple to double! We often use two 21-ounce cans of blueberry pie filling for a richer, more substantial cake that lasts longer. If doubling, ensure your slow cooker is large enough (a 6-quart or larger is ideal). Keep an eye on the cooking time, as it might take slightly longer, and remember to switch your slow cooker to the “warm” setting once done to maintain its temperature without overcooking.
- Sugar-Free Alternative: For those monitoring sugar intake, use a sugar-free lemon cake mix and a sugar-free blueberry pie filling. The result will still be a wonderfully sweet and tangy dessert.
Tips for the Best Crockpot Lemon Blueberry Dump Cake
Achieving the perfect dump cake is easy, but a few small tips can elevate your dessert from good to absolutely incredible:
- Don’t Forget the Non-Stick Spray: A generous coating of non-stick spray in your Crockpot is essential. It ensures your delicious lemon blueberry cake slides out easily for serving and makes cleanup significantly simpler – no more stubborn sticky bits!
- Embrace the Toppings: While fantastic on its own, this cake truly shines with the right accompaniments. A scoop of creamy vanilla ice cream, a dollop of fresh whipped cream, or a sprinkle of fresh lemon zest and blueberries will take it to the next level. The cold, creamy toppings provide a delightful contrast to the warm, fruity cake.
- Resist Stirring: It’s called a “dump cake” for a reason! Once the layers are in, resist the urge to stir. The magic happens as the ingredients slowly combine and cook without interference, creating distinct and delicious layers.
- Patience is a Virtue: Slow cooking is all about patience. Allow your cake to cook fully on the low setting. Opening the lid frequently releases heat and extends the cooking time.
When and What to Serve with Your Dump Cake
The beauty of this sweet and tart lemon blueberry dump cake is its versatility. Enjoy it as a delightful breakfast or brunch treat, a satisfying coffee or tea snack, or a comforting indulgence after dinner. It’s truly suitable for any occasion!
